LIQUID JSISI'ENSIN'G APPARATUS Original 1T0, 1,775,441, dated September9, 1980, Serial 110.461422, filed June 16, 1930. Application reissuefiled September 3, 1982. Serial No. 831,741.

This invention relates to apparatus of the type in which asoline orother liquid is delivered throng a flexible hose under control of anozzle valve.

The objects of the invention are to provide simple, practical andefiicient mechanism for throwin a switch, or operating a valve or otherfrom the nozzle end of the hose.

One of the important features of the invention is the provision of meansby which pulling on the hose is made effective to operate the desiredcontrol mechanism.

Other novel features of the invention will appear as the specificationproceeds.

The drawing accompanyingand forming part of the specificationillustrates several difierent forms the invention may take, but itshould be understood that the structure may otherwise vary withoutdeparture from the true spirit and broad scope of the invention. r

Fig. 1 is a general side view showing the invention incorporated ina'gasoline disensing pump or stand. Figs. 2 and 3 are roken details ofthe control means shown in Fig. 1; Figs. 4 and 5 are broken detailsillustrating other embodiments of the invention.

The resent invention is a continuation in part 0 applications 323,411,filed December 3, 1928, and 324,761, filed December 8,1928, and issuedas Patents 1,713,102 of May 14, i 1929, and 1,717,274 of June 11, 1929,respeci tively.

In the first illustrated form of the invention, Figs. 1, 2 and 3, thecontrol is efiected by means of hose 7 through the medium of anextensible or telescopic section rovided I at the upper end of the hoseand s own as ow governing mechanism" for the pump motor will be operatedto impel a flow of liquid through the supply pipe 12,

meter 16 and hose 7 The amount of liquld delivered may be accuratelydetermined by a nozzle valve 17 at the discharge end of the hose and thepump may be started and stopped by pulling or releasing the pull on thehose, a return spring such as indicated at 18 being provided to turn offthe switch and the valve and to retract the hose when pull on the sameis released. This return spring is made heavy enough to accomplish thispurpose and it is shown as directly con nected to one arm of the bellcrank lever 10. To facilitate the extension and contraction of the hosejoint and prevent wear on the sylphon, the hose is shown as havingacollar 19 at its upper end slidingly fittin over a neck 20 on the elbowor goose nec 21 at the upper end of the hose line.

.In the second embodiment illustrated, the switch and valve are operatedby a straight lever 22 connected by a link- 23 with a band '24encircling the suspended'portion of the with a lever 29 operating asupply valve 30 in i the flow line and engaging the operating lever 31of the switch 32, which controls the pump motor.

In all forms of the invention, it will be observed that the flowoperation may be governed by simply pulling on the hose to start 'thefiow and by releasing pull on the hose to stop the flow. The naturalefiect'of the hose to swing straight down from the goose-neck at the topwill have a. tendency to restore the parts in Figs. 4 and 5, but thisshutting ofi operation may be made certain by the suitable returnsprings 25 and 33. The parts may be arranged, so that pull on theswinging portion of the hose in any direction will be efiec tive tothrow the switch or operate the valve, or both, so that the attendantmay conveniently actuate the control no matter in what position he maybe standing or no matter what position he may be in regard .to the pumpstand. In constructions like those shown in Figs. 4 and 5, it will beevident, the same control may be effected by a push action on the hosetoward the left in these views instead of a straight pull toward theleft, so that the attendant may accomplish the same control ,eflectseither by pulling toward the left or if he be at the right of the standby pushing back on thehose, so as to effect the deflection on the hoseas indicated in the dotted lines in Fig. 4. It will be understoodtherefore that the invention comprehends the deflection or shifting ofthe hose adjacent its supported end to effect mechanical actuation ofthe flow control mechanism, whether the latter be a switch or some otherform of device. By this invention, the attendant at a pump stand isenabled to deliver continuously any desired volumes of liquid by simplyoperating the nozzle valve to start or to stop the flow and by using thehose in effect as a mechanical handle for throwing the switch or othercontrol to start and stop the pump motor or the like, the meter at thepump stand at all times showing the amounts delivered in this way. Theinvention also involves a safety feature in that in the formsillustrated, the pump motor is automatically shut off as soon as theactuating pull on the hose is released. Inattention or carelessness onthe part of the operator therefore. results in the flow being shut off.The terms employe'd herein are used in a descriptive rather than in alimiting sense, it being understood that equivalents may be employed asfor in stance, in place of the return springs 18, 25 and 33,counter-balance weights, pressure actuated means or the like, may beused.

What is claimed is 1. A liquid metering and delivery system comprising aliquid delivery line terminating in a flexible hose, suspended forpulling movement and having a manually operable nozzle Y valve by whichdischarge of liquid from the hose may be accurately determined, an elecvtric pump for supplying liquid under pressure ;through said deliveryline and hose, a meter in the delivery line for showing the amounts ofliquid delivered by the hose under control of said nozzle valve, aswitch for starting and stopping the electric pump and flexiblemechanicalconnections from said susjpended pull portion of the hose tosaid switch for operating the latter to start and stop the pump bypulling movements on the hose, and whereby various desired quantities ofliquid may be measured. and deliwlipd by control exercised at the nozzleend of the hose and the hose be drained by operation of the nozzle valveafter shutting off the pump and the hose be left free of pressure aftereach delivery.

2A liquid metering and delivery system comprising a liquid delivery lineterminating in a flexible hose, suspended for pulling movement andhaving a manually operable nozzle valve by which discharge of liquidfrom the hose may be accurately determined, an electric pump forsupplying liquid under pressure through said delivery line and hose, a

meter in the delivery line for showing the amounts of liquid deliveredby the hose under control of said nozzle valve, a switch for startingand stopping the electric pump and flexible mechanical connections fromsaid suspended pull portion of the hose to said switch for operating thelatter to start and stop the pump by pulling movements on the hose, andwhereby various desired quantities of liquid may be measured anddelivered by control exercised at the nozzle end of the hose and thehose be drained by operationeof the nozzle valve after shutting off thepump and the hose be left free of pressure after each delivery and valvemeans in said system connected to be actuated by said hose pull conberto said switch so that by pulling the said conduit outwardly from thestand the switch will be moved to starting position, and means forrestoring the switch to stopping position when the pull on the conduitis released.
